Someday, there will be historical fantasy set in our time. Here are some thoughts on what its cliches might be:

The Gruff Guide to Electrical Age North America

Transportation: In the countryside, all travel is by steam-powered trains or gasoline-powered flying cars.

Most urban travel is in ground cars driven by wise old men. (Often these "cabbies" turn out to be beautiful young women in disguise.)

The adventurous might take underground subway trains powered by fission reactors. Your fellow passengers may include land pirates and "goths" (more properly called shoggoths). Be prepared to defend yourself, your possessions, and your sanity.

Food: In the countryside, be certain to bring a tin-opener (aka "churchkey"), and sufficient tins of stew. In much of North America you will be able to hunt rabbits, llamas, and wallabies and add them to the stew.

In cities, you will eat in diners or in ristorantes. In a diner, the waitron will heat a tin of stew and open it for you. In a ristorante, you will eat more varied fare such as fish served complete with heads, meatloaf made from tofu plants, and German tacos.
